Indoor augmented reality information display method

Abstract

The present invention relates to an indoor augmented reality information display method, system and terminal. The method comprises the steps: acquiring position information of a first target; and if a matching degree of the position information of the first target and preset position information is more than a preset threshold, acquiring information from an information database, and displaying the information. By using the indoor augmented reality information display method, system and terminal provided by the present invention, the position information of the first target can be automatically acquired, so that data collection time and cost are saved, and efficiency is improved; value-added service is provided by fully using positioning information; and meanwhile, the information is displayed only after a corresponding condition is met, so that information display accuracy is improved, and thus wrong information is prevented from being displayed, and user experience is further enhanced.
